Technology Of Near Digital Sample DRFM

In electronic warfare, modern pulse compressed radar makes the simple deception jamming useless because of its complicated in-pulse modulation technology. With the increasing requirements of anti-jamming of radars, the deception jamming of distance, even distance and velocity synchronously, to the correlative radars is needed imminently, and that makes memory frequency technology, especially the digital radio frequency memory develop rapidly.Combined with the jamming modulation technology, the classification, basic configuration and operation principle are introduced from the view of the application of electronic jamming. The sample pulse DRFM principle phase correction advantages and disadvantages are introduced either. Technology of near digital sample DRFM is proposed based on the traditional full pulse DRFM and sample pulse DRFM. The jamming of modern compressed radar is simulated based on the analysis and research on near digital sample DRFM. The simulation results indicates that near digital sample DRFM is a powerful means of jamming to the modern pulse compressed radar.
